The invention discloses an output power detection device for a medical short-wave therapeutic instrument. The output power detection device comprises a light energy conversion assembly, wherein the light energy conversion assembly is electrically connected with an electrode plate so as to convert the output power of the short-wave therapeutic instrument into the light energy; and an illuminance detection assembly which is used for measuring the illuminance of the light energy conversion assembly, and measuring and calibrating the output power of the short-wave therapeutic instrument accordingto the illuminance, detected by the illuminance detection assembly, of the light energy conversion assembly and the preset corresponding relation between the illuminance value and the output power. According to the invention, the output power of the short-wave therapeutic instrument is converted into light energy through the connection of the light energy conversion assembly and the electrode slice, the illuminance of the light energy conversion assembly is measured through the illuminance detection assembly, and the output power of the short-wave therapeutic instrument is calibrated accordingto the detected illuminance, the illuminance value and the preset corresponding relation of the output power. The device does not interfere with a resonance circuit of the short-wave therapeutic instrument, and is small in error and accurate in detection result.
Description
technical field [0001] The invention relates to the technical field of output power testing devices, and more specifically, relates to an output power testing device of a medical short-wave therapeutic apparatus. Background technique [0002] The output signal frequency of the medical short-wave therapy device is 27.12MHz, the power is 200W, and the wavelength is 7.06 meters. Usually, in order to detect the power of the output signal of the short-wave therapy device, there are generally three methods as follows: [0003] 1. Connect resistor R in parallel at the output end of the short-wave therapeutic apparatus, test the current value I on the signal line by connecting a high-frequency ammeter in series with the output signal line, and calculate the output power of the short-wave therapeutic apparatus according to the power W=I2*R; However, the disadvantage of this method is that the ammeter is connected in series in the signal line, which will affect the distributed capacit...
